I. IntroductionWater canal treatment is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. First, we have an idea to use black carbon, filtration sand, rocks, and pebbles. The black carbon will help the canal water to remove the bad odor of the canal water. Filtration sand has three types: rapid sand filter, upflow sand filter, and slow sand filter. Slow sand filter is like the white sand that doesn’t need chemicals to produce high quality of water so we chose slow sand filter. Rocks and pebbles contain inorganic minerals that can dissolve sulfates and other chemicals of the canal water. We decided to do this process by layer to layer using bottles. We also used cotton cloth per layer and filter paper in the black carbon and filtration sand.

Water Quality and Water Management
What determines water quality?
Drinking water should be colorless, odorless and flavorless; this means that there are no organisms and sediments in the water, but it does not mean that if your drinking water look, smells and taste clean, that does not mean that there is nothing else it.
Water also contains dissolved solids:
•Sulfur
•Calcium
•Magnesium
If water contains a lot of dissolved calcium and magnesium it is called hard water. But soft water contains less calcium and magnesium.
Dissolved solids are just one factor that can affect water quality.
Different ways how humans activities can affect water quality:
People are part of the water cycle. We take fresh water from rivers, lakes and underground. We use it for different purposes. All of these activities add substances to the water and many of these substances are pollutants that can harm living things.
Such as:
•Urban run-off
•Air Pollution
•Industrial Waste
•Treated Sewage
•Oil Spills
Some pollutants occur naturally in the environment and others do not. People add substances to the water that do not occur naturally in the environment. These are called Toxic substances.
Toxic Substances are used for:...

...﻿Purification of Water
Domestic:
Distillation - In the process of distillation water is heated and evaporation takes place, whereby water changes back to water when cooled; this process is called condensation. The condensed water is the purest form of water, free from microbes, and impurities.
Boiling - Boiling is the best and simplest method to purify water. After straining the water twice through clean muslin cloth, it is boiled for ten minutes lo kill the microbes present in it and also remove the temporary hardness of water.
Filtration - Different varieties of filters are used to purify the water at domestic level. Filter rods can be installed. These rods are made of china porcelain and it is porous and hollow from the centre. When water is put through it, it is purifies and drips in out clean into a small tank, ready for use.
Industrial:
This water is usually purified by huge tanks, which are either carbon, sand and or multi media based. The water passes through a mesh screen to remove big parts. Chemicals are then added to make solids and microbes fall to the bottom. The water is then filtered through gravel beds to remove all solids and finally it is chlorinated to kill off any harmful microbes left.

Water and Electrolytes
Water constitutes 50-55% of a woman's body weight and 55-60% of man's weight. Water gives structure and form to the body, helps maintain body temperature, and also creates the necessary environment for cell metabolism. There are two compartments of body water, extracellular and intracellular fluid. Extracellular fluid (ECF) is water found outside of cells. Making up approximately 20% of total body weight, the ECF consists of blood plasma, interstitial fluid surrounding the cells, secretory fluid, which is water in transit, and dense tissue fluid, which is water located within dense connective tissue such as cartilage and bone. Intracellular fluid (ICF) is the water inside the cells. It makes up 35-40% of total body weight.
Water Balance
The maintenance of correct proportions of ECF and ICF is vital to proper functioning of the body, as can be seen below in Clinical Problems. The body maintains fluid balance by calibrating water intake, excretion, and internal processes controlling water distribution.
Water Intake (Thirst)
The thirst mechanism in animals is a complex interaction of control centers in the brain and hypothalamus; though the details of that mechanism go well beyond the scope of this SparkNote, it is important to...

...TAINTED WATER
ChemMatters February 1988 (page 13-15)
“Water itself doesn't conduct electricity; it's the minerals in it that conduct the electricity, not the water.”
* When a tap water was produced to an electrical device with a pair of probes and a light bulb, the bulb immediately beamed. The reason for this to happen is the presence of minerals in water. However, when this was tested with distilled water, it was observed that the light bulb did not beam. This proves that water by itself is not a conductor of electricity, but it’s the minerals.
* When a tap water was tested using a precipitator, the tap water took on a yellow hue and in minutes a brownish scum covered the surface of the water. However, after a thorough experiment, the reason for the appearance of this brownish scum was discovered. The scummy precipitate was formed of ions that came directly from the precipitator, not from the tap water.
* When the current is on, the iron electrode becomes the anode and the iron is oxidized:
Fe(s) Fe3+ (aq) + 3e-
The aluminum electrode was the cathode. Here, water was decomposed to from hydrogen gas and hydrogen ions:
2H2O (1) + 2e- H2 (g) + 2OH-(aq)
In conclusion, all the scum formed was due to the “precipitator”, not ions in the tap water.

WATER ESSAY
The first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. Water covers about 3/4 of the earth. In nature, water naturally exists in all three physical states of matter—solid, liquid and gas. Water's extraordinary properties are emergent properties resulting from water's structure and molecular interactions. Living cells are 70%-95% H2O
The simple structure of H2O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pulls hydrogen's electrons towards it, causing oxygen to become partial negative. The hydrogen atoms then will have fewer electrons towards its own nucleus, therefore making it partial positive. Since positive charge and negative charge attracts each other, the molecular formation of H2O will result hydrogen bonding.
Each water molecule can form hydrogen bonds to a maximum of four other water four molecules. Organisms Depend on the Cohesion of Water Molecules Hydrogen bonds hold water...

...Properties of Water
We live on a planet that is dominated by water. More than 70% of the Earth's surface is covered with this simple molecule. Scientists estimate that the hydrosphere contains about 1.36 billion cubic kilometers of this substance mostly in the form of a liquid (water) that occupies topographic depressions on the Earth. The second most common form of the water molecule on our planet is ice. If all our planet's ice melted, sea-level would rise by about 70 meters.
Water is also essential for life. Water is the major constituent of almost all life forms. Most animals and plants contain more than 60% water by volume. Without water life would probably never have developed on our planet.
Water has a very simple atomic structure. This structure consists of two hydrogen atoms bonded to one oxygen atom (Figure 8a-1). The nature of the atomic structure of water causes its molecules to have unique electrochemical properties. The hydrogen side of the water molecule has a slight positive charge (see Figure 8a-1). On the other side of the molecule a negative charge exists. This molecular polarity causes water to be a powerful solvent and is responsible for its strong surface tension (for more information on these two properties see the discussion below).
When the water molecule makes a...

...The Panama Canal: Its History &amp; Its Legacy
Throughout world history, numerous modes of transportation were utilized in order for people to get from one place to another. For water transportation, people had different options to get from one place to another. For short distances, they could use boats or canoes. In contrast, if someone had to travel a long ways to get to their destination, the definitive choice would be to utilize ships. Ever since ships were invented, explorers from all over the world have sailed the open seas in the hopes of discovering new places and possibly bringing something valuable back to their home land. For the most part, there weren’t any major issues that hindered the water exploration process. There were some difficulties, however, when it came to crossing from one body of water to the next in certain parts of the world. It is because of this dilemma that canals were built at key intersections of water highways. Some notable canals that have been constructed throughout history include the Suez Canal (connecting the Mediterranean Sea and the Red Sea at Egypt) in 1869 and the Kiel Canal (linking the Baltic Sea and the North Sea at Germany) in 1895. However, there is one canal that bears the most significance of them all and has saved more time, money, and effort for ocean-going vessels than the other...
